The Obama administration announced an amendment to an executive order Thursday that introduces targeted sanctions on Russian assets here in the United States. The sanctions come in response to reported cyber attacks on the Democratic National Committee and other groups by Russian-backed hackers.

“President Obama authorized a number of actions in response to the Russian government’s aggressive harassment of U.S. officials and cyber operations aimed at the U.S. election in 2016,” said the White House in a statement. “Russia’s cyber activities were intended to influence the election, erode faith in U.S. democratic institutions, sow doubt about the integrity of our electoral process, and undermine confidence in the institutions of the U.S. government. These actions are unacceptable and will not be tolerated.”
